The Ergo non-concussive basin mixer tap is designed and manufactured from the highest quality materials. Time Delay Self-Closing taps are operated by simply pushing the tap and water is dispensed. Allowing the user a more controlled use of their water, this timer tap turns off automatically after a set period of time, which not only reduces the risk of people leaving the tap on and flooding an area but can be extremely cost effective as well. This style of tap can be used in a domestic system but is most commonly found in public/commercial settings. Easy to use and adjust temperature.
